How hot does it get in the frunk on the highway?
Temperature will be mild in the morning, but I have something in the front that I do not want to get too hot. What has been your experience with traveling on the highway? Does the frunk get over 100°?

Trunk gets warm but front trunk?
does the frunk get over a hundred degrees?
put a thermometer and put it in there would probably be the best at determining and would be dependent on outside temperature too?
put some frozen ice packs in there for cooling?
Might work

those frozen packs are a good idea. Too late for anything else because I'm on my way. I will see how hot it is when I get there.

no issue with food shopping in my 25 e trunk with a 35 minute ride home in florida heat , i would not ever leave an aerosol can in there . On long hauls with anything iffy it goes in the fronk .....now getting the fronk auto pull down to work 100 % is another story even after the dealer just replaced the latch .

I drove for about an hour and a half with a small generator up in the front. I'm always a little bit extra careful when gasoline is involved. I did not remove it right away, but I did not notice any heat at all coming from the front after that Highway drive.

I did a 275 mile round trip to Arizona and back today with our corvette club. I kept sodas and waters cooled by a couple of ice packs in a Playmate Igloo in my E-Ray frunk. After 10 hours the drinks were still ice cold but our snacks kept out of the Igloo in the frunk were quite warm. I wouldn’t keep any chocolates or makeup for your wife in there.

I would think it would be ambient dependent.
Here? (70F) probably not so bad.
Death Valley on Fri/Sat coming up? (116F) maybe not so much. LOL!

On a recent road trip I measured 118F in the frunk on my Z06. This was roughly a 7-8 hour driving day, no real hammering on it, with the front license plate filler removed for max airflow, and probably mid 90s ambient. I had previously measured 112F on my previous 25 E-Ray in the frunk over a similar drive with lower ambient temps (May of last year, mid 80s ambient) and front plate filler still installed.
FYI, I also installed the euro underbody air deflecors on my Z, and while I don’t have pre-install temps, the trunk on a 12 hour driving day, with low 90s ambient temps was only 106F. So the euro air deflectors do seem to help keep the trunk cooler. Our luggage, while warm, was noticeably less hot than I’ve noticed on previous C8 road trips.

For everyday stuff on longer trips I might be worried about I have an insulated cooler bag similar to this (xxl - 23x14x15):
I also found that most 40 can soft coolers fit perfectly with room on top for true cooling needs.
